Nitrate ion association with Nd3+

摘要

The overall stability constantsK1andK2of NdNO32+and Nd(NO3)2+complexes were determined (K1=1.77;K2=1.28) using an extraction method with tri-n-butyl phosphate as the extractant. The ratio β1/β2of the stepwise stability constants is discussed. It was established that the Nd(NO3)2+complex was an outer-sphere ion pai
